Ok.. on the suggestion of Dion, here's my experience of installing Coppermine and bridging it to my phpbb forum.
I need to preface this with some info.
I am a novice when it comes to coding of any kind (see my previous problem for supporting evidence ), I get by and fortunately have worked out where to go for help when I need it.
The basic install was as easy as I'd hoped, went very smooth.
Managing the config was a little tedious but I got there (only had to redo it completely once, followed by a couple of tweaks)
As advised, I tested it standalone before attempting bridging and it all looked as it should.
The bridging gave me some problems. These were largely due to the groups settings (I'd checked the box to use the group settings from our board)
On my forum our admin team are not in the Administrators group. This meant that when I finished the bridging I wasn't authorised to do anything and was seen as a regular user.
To get over this I added myself to the Administrators group. First time round I used it as a secondary group but needed to have it as my primary.
Once I'd done that, everything was great.
Added the link to my forum header and announced it to my users.
It'd be great to get some proper integration, my users are already asking for embedding options (there is a plugin but it was written for software version 1.4 and the current is 1.5) so I'm hoping someone (Dion.. here's my plea ) will get round to it.
This is my forum http://www.oldschoolmtb.org.uk/forum/index.php
And the gallery http://www.oldschoolmtb.org.uk/gallery/
Only changes I've made are to the favicon(s) and logo. The style isn't quite right but it's close enough for me not to worry about.
It's early days yet, less than 24hours in, and I need to dig out my hdd with my pics on so I can get some albums started.
Hopefully my users will populate it and make the effort worthwhile.
